Description

本地路由授权的方法、 装置和系统 技术领域
本发明涉及通信技术领域, 特别涉及一种本地路由授权的方法、 装置和系统。 背景技术 说
随着通信技术的发展, 移动通信网络也越来越先进。 其中, 基于 IEEE ( Institute of Electrical and Electronic Engineers, 电气电子工程师学会) 802. 16无线接入技术的移 云力 WiMAX (Worldwide Interoperabi l ity for Microwave Access, 微波接入全球互通网络) 由于能够为用户提供高速的数据传输能力, 而受到了书广泛的关注。
在移动 WiMAX网络中, 当 MS (Mobi le Station, 移动终端) 与外部网络之间传输业务 流时, MS 发送的上行业务流一般经过 BS (Base Station, 基站) 传送到 Serving ASN-GW ( Serving Access Service Network Gateway, 月艮务接入网关), Serving ASN—GW再传送至 lj Anchor ASN-GW (锚定接入网关), 最后经过 HA (Home Agent, 家乡代理) 传送到外部网络 中, 外部网络发送的下行业务流则经过与上行业务流反方向的承载路径路由到 MS上。 参见 图 1, 当两个 MS (MSI和 MS2 ) 之间采用上述的方法传输业务流时, 如果 MS1和 MS2由同一 个 Serving ASN-GW管理, 两者之间传输业务流的路径如图 1中的虚线所示, 从图 1可以看 出业务流传输路径从 Serving ASN-GW到 HA之间会发生重叠, 从而产生传输路径冗余, 造 成不必要的业务流传输时延和核心网传输负载。 为此, 提出了通过 LR ( Local Routing, 本 地路由) 传输 MSI和 MS2之间的业务流, 具体地如图 1中的实线所示, Serving ASN-GW直 接将业务流从 MS1传输给 MS2, 或直接将业务流从 MS2传输给 MS1。
然而, 在实现本发明的过程中, 发明人发现现有技术至少存在以下问题:
现有技术中网络侧一般仅需要根据一个 MS的 QoS ( Qual ity of Service, 服务质量) 签约信息或运营商策略对该 MS的业务流进行授权, 而本地路由中涉及到二个 MS, 因此现有 技术无法满足对本地路由进行授权的需求。 发明内容
为了满足对本地路由进行授权的需求, 本发明实施例提供了一种本地路由授权的方法、 装置和系统。 所述技术方案如下: 一种本地路由授权的方法, 所述方法包括:
根据第一移动终端的业务流信息, 或根据第一移动终端和第二移动终端的业务流信息, 分别向第一本地路由策略实体和第二本地路由策略实体发起本地路由授权请求, 使得所述 第一本地路由策略实体对所述第一移动终端进行本地路由授权, 所述第二本地路由策略实 体对第二移动终端进行本地路由授权;
当所述第一移动终端和所述第二移动终端的本地路由授权结果均为成功后, 通过本地 路由传输所述第一移动终端的业务流信息对应的业务流和所述第二移动终端的业务流信息 对应的业务流。
一种本地路由授权的装置, 所述装置包括:

本地路由传输模块, 用于当所述第一移动终端和所述第二移动终端的本地路由授权结 果均为成功后, 通过本地路由传输所述第一移动终端的业务流信息对应的业务流和所述第 二移动终端的业务流信息对应的业务流。
一种本地路由授权的系统, 所述系统包括:
本地路由执行实体、 第一本地路由策略实体和第二本地路由策略实体;
所述本地路由执行实体, 用于根据第一移动终端的业务流信息, 或者根据第一移动终 端和第二移动终端的业务流信息, 分别向所述第一本地路由策略和所述第二本地路由策略 发起本地路由授权请求; 当所述第一移动终端和所述第二移动终端的本地路由授权结果均 为成功后, 通过本地路由传输所述第一移动终端的业务流信息对应的业务流和所述第二移 动终端的业务流信息对应的业务流;
所述第一本地路由策略实体, 用于在接收到所述本地路由执行实体发起的本地路由授 权请求后, 对所述第一移动终端进行本地路由授权;
所述第二本地路由策略实体, 用于在接收到所述本地路由执行实体发起的本地路由授 权请求后, 对所述第二移动终端进行本地路由授权。
本发明实施例提供的技术方案的有益效果是:
通过根据第一移动终端的业务流信息, 或第一移动终端和第二移动终端的业务流信息, 对第一移动终端和第二移动终端进行本地路由授权, 实现了对本地路由进行授权, 可以满 足对本地路由进行授权的需求。 附图说明
